Book IV, Chapter IV

Of the Tendency of Profits to a Minimum

IV.4.1

§1. The tendency of profits to fall as society advances, which has been brought to notice in the preceding chapter, was early recognized by writers on industry and commerce; but the laws which govern profits not being then understood, the phenomenon was ascribed to a wrong cause. Adam Smith considered profits to be determined by what he called the competition of capital; and concluded that when capital increased, this competition must likewise increase, and profits must fall. It is not quite certain what sort of competition Adam Smith had here in view. His words in the chapter on Profits of Stock*14 are, "When the stocks of many rich merchants are turned into the same trade, their mutual competition naturally tends to lower its profits; and when there is a like increase of stock in all the different trades carried on in the same society, the same competition must produce the same effect in them all." This passage would lead us to infer that, in Adam Smith's opinion, the manner in which the competition of capital lowers profits is by lowering prices; that being usually the mode in which an increased investment of capital in any particular trade, lowers the profits of that trade. But if this was his meaning, he overlooked the circumstance, that the fall of price, which if confined to one commodity really does lower the profits of the producer, ceases to have that effect as soon as it extends to all commodities; because, when all things have fallen, nothing has really fallen, except nominally; and even computed in money, the expenses of every producer have diminished as much as his returns. Unless indeed labour be the one commodity which has not fallen in money price, when all other things have: if so, what has really taken place is a rise of wages; and it is that, and not the fall of prices, which has lowered the profits of capital. There is another thing which escaped the notice of Adam Smith; that the supposed universal fall of prices, through increased competition of capitals, is a thing which cannot take place. Prices are not determined by the competition of the sellers only, but also by that of the buyers; by demand as well as supply. The demand which affects money prices consists of all the money in the hands of the community, destined to be laid out in commodities; and as long as the proportion of this to the commodities is not diminished, there is no fall of general prices. Now, howsoever capital may increase, and give rise to an increased production of commodities, a full share of the capital will be drawn to the business of producing or importing money, and the quantity of money will be augmented in an equal ratio with the quantity of commodities. For if this were not the case, and if money, therefore, were, as the theory supposes, perpetually acquiring increased purchasing power, those who produced or imported it would obtain constantly increasing profits; and this could not happen without attracting labour and capital to that occupation from other employments. If a general fall of prices, and increased value of money, were really to occur, it could only be as a consequence of increased cost of production, from the gradual exhaustion of the mines.

IV.4.2

It is not tenable, therefore, in theory, that the increase of capital produces, or tends to produce, a general decline of money prices. Neither is it true, that any general decline of prices, as capital increased, has manifested itself in fact. The only things observed to fall in price with the progress of society, are those in which there have been improvements in production, greater than have taken place in the production of the precious metals; as for example, all spun and woven fabrics. Other things, again, instead of falling, have risen in price, because their cost of production, compared with that of gold and silver, has increased. Among these are all kinds of food, comparison being made with a much earlier period of history. The doctrine, therefore, that competition of capital lowers profits by lowering prices, is incorrect in fact, as well as unsound in principle.

IV.4.3

But it is not certain that Adam Smith really held that doctrine; for his language on the subject is wavering and unsteady, denoting the absence of a definite and well-digested opinion. Occasionally he seems to think that the mode in which the competition of capital lowers profits, is by raising wages. And when speaking of the rate of profit in new colonies, he seems on the very verge of grasping the complete theory of the subject. "As the colony increases, the profits of stock gradually diminish. When the most fertile and best situated lands have been all occupied, less profit can be made by the cultivators of what is inferior both in soil and situation." Had Adam Smith meditated longer on the subject, and systematized his view of it by harmonizing with each other the various glimpses which he caught of it from different points, he would have perceived that this last is the true cause of the fall of profits usually consequent upon increase of capital.

IV.4.4

§2. Mr. Wakefield, in his Commentary on Adam Smith, and his important writings on Colonization, takes a much clearer view of the subject, and arrives, through a substantially correct series of deductions, at practical conclusions which appear to me just and important; but he is not equally happy in incorporating his valuable speculations with the results of previous thought, and reconciling them with other truths. Some of the theories of Dr. Chalmers, in his chapter "On the Increase and Limits of Capital," and the two chapters which follow it, coincide in their tendency and spirit with those of Mr. Wakefield; but Dr. Chalmers' ideas, though delivered, as is his custom, with a most attractive semblance of clearness, are really on this subject much more confused than even those of Adam Smith, and more decidedly infected with the often refuted notion that the competition of capital lowers general prices; the subject of Money apparently not having been included among the parts of political economy which this acute and vigorous writer had carefully studied.

IV.4.5

Mr. Wakefield's explanation of the fall of profits is briefly this. Production is limited not solely by the quantity of capital and of labour, but also by the extent of the "field of employment." The field of employment for capital is twofold; the land of the country, and the capacity of foreign markets to take its manufactured commodities. On a limited extent of land, only a limited quantity of capital can find employment at a profit. As the quantity of capital approaches this limit, profit falls; when the limit is attained, profit is annihilated; and can only be restored through an extension of the field of employment, either by the acquisition of fertile land, or by opening new markets in foreign countries, from which food and materials can be purchased with the products of domestic capital. These propositions are, in my opinion, substantially true; and, even to the phraseology in which they are expressed, considered as adapted to popular and practical rather than scientific uses, I have nothing to object. The error which seems to me imputable to Mr. Wakefield is that of supposing his doctrines to be in contradiction to the principles of the best school of preceding political economists, instead of being, as they really are, corollaries from those principles; though corollaries which, perhaps, would not always have been admitted by those political economists themselves.

IV.4.6

The most scientific treatment of the subject which I have met with is in an essay on the effects of Machinery, published in the Westminster Review for January 1826, by Mr. William Ellis:*15 which was doubtless unknown to Mr. Wakefield, but which had preceded him, though by a different path, in several of his leading conclusions. This essay excited little notice, partly from being published anonymously in a periodical, and partly because it was much in advance of the state of political economy at the time. In Mr. Ellis's view of the subject, the questions and difficulties raised by Mr. Wakefield's speculations and by those of Dr. Chalmers, find a solution consistent with the principles of political economy laid down in the present treatise.

IV.4.7

§3. There is at every time and place some particular rate of profit, which is the lowest that will induce the people of that country and time to accumulate savings, and to employ those savings productively. This minimum rate of profit varies according to circumstances. It depends on two elements. One is, the strength of the effective desire of accumulation; the comparative estimate, made by the people of that place and era, of future interests when weighed against present. This element chiefly affects the inclination to save. The other element, which affects not so much the willingness to save as the disposition to employ savings productively, is the degree of security of capital engaged in industrial operations. A state of general insecurity no doubt affects also the disposition to save. A hoard may be a source of additional danger to its reputed possessor. But as it may also be a powerful means of averting dangers, the effects in this respect may perhaps be looked upon as balanced. But in employing any funds which a person may possess as capital on his own account, or in lending it to others to be so employed, there is always some additional risk, over and above that incurred by keeping it idle in his own custody. This extra risk is great in proportion as the general state of society is insecure: it may be equivalent to twenty, thirty, or fifty per cent, or to no more than one or two; something, however, it must always be: and for this, the expectation of profit must be sufficient to compensate.

IV.4.8

There would be adequate motives for a certain amount of saving, even if capital yielded no profit. There would be an inducement to lay by in good times a provision for bad; to reserve something for sickness and infirmity, or as a means of leisure and independence in the latter part of life, or a help to children in the outset of it. Savings, however, which have only these ends in view, have not much tendency to increase the amount of capital permanently in existence. These motives only prompt persons to save at one period of life what they purpose to consume at another, or what will be consumed by their children before they can completely provide for themselves. The savings by which an addition is made to the national capital usually emanate from the desire of persons to improve what is termed their condition in life, or to make a provision for children or others, independent of their exertions. Now, to the strength of these inclinations it makes a very material difference how much of the desired object can be effected by a given amount and duration of self-denial; which again depends on the rate of profit. And there is in every country some rate of profit, below which persons in general will not find sufficient motive to save for the mere purpose of growing richer, or of leaving others better off than themselves. Any accumulation, therefore, by which the general capital is increased, requires as its necessary condition a certain rate of profit; a rate which an average person will deem to be an equivalent for abstinence, with the addition of a sufficient insurance against risk. There are always some persons in whom the effective desire of accumulation is above the average, and to whom less than this rate of profit is a sufficient inducement to save; but these merely step into the place of others whose taste for expense and indulgence is beyond the average, and who, instead of saving, perhaps even dissipate what they have received.

IV.4.9

I have already observed that this minimum rate of profit, less than which is not consistent with the further increase of capital, is lower in some states of society than in others; and I may add, that the kind of social progress characteristic of our present civilization tends to diminish it. In the first place, one of the acknowledged effects of that progress is an increase of general security. Destruction by wars, and spoliation by private or public violence, are less and less to be apprehended; and the improvements which may be looked for in education and in the administration of justice, or, in their default, increased regard for opinion, afford a growing protection against fraud and reckless mismanagement. The risks attending the investment of savings in productive employment require, therefore, a smaller rate of profit to compensate for them than was required a century ago, and will hereafter require less than at present. In the second place, it is also one of the consequences of civilization that mankind become less the slaves of the moment, and more habituated to carry their desires and purposes forward into a distant future. This increase of providence is a natural result of the increased assurance with which futurity can be looked forward to; and is, besides, favoured by most of the influences which an industrial life exercises over the passions and inclinations of human nature. In proportion as life has fewer vicissitudes, as habits become more fixed, and great prizes are less and less to be hoped for by any other means than long perseverance, mankind become more willing to sacrifice present indulgence for future objects. This increased capacity of forethought and self-control may assuredly find other things to exercise itself upon than increase of riches, and some considerations connected with this topic will shortly be touched upon. The present kind of social progress, however, decidedly tends, though not perhaps to increase the desire of accumulation, yet to weaken the obstacles to it, and to diminish the amount of profit which people absolutely require as an inducement to save and accumulate. For these two reasons, diminution of risk and increase of providence, a profit or interest of three or four per cent is as sufficient a motive to the increase of capital in England at the present day, as thirty or forty per cent in the Burmese Empire, or in England at the time of King John. In Holland during the last century a return of two per cent on government security, was consistent with an undiminished, if not with an increasing, capital. But though the minimum rate of profit is thus liable to vary, and though to specify exactly what it is would at any given time be impossible, such a minimum always exists; and whether it be high or low, when once it is reached, no further increase of capital can for the present take place. The country has then attained what is known to political economists under the name of the stationary state.

IV.4.10

§4. We now arrive at the fundamental proposition which this chapter is intended to inculcate. When a country has long possessed a large production, and a large net income to make savings from, and when, therefore, the means have long existed of making a great annual addition to capital; (the country not having, like America [1848], a large reserve of fertile land still unused;) it is one of the characteristics of such a country, that the rate of profit is habitually within, as it were, a hand's breadth of the minimum, and the country therefore on the very verge of the stationary state. By this I do not mean that this state is likely, in any of the great countries of Europe, to be soon actually reached, or that capital does not still yield a profit considerably greater than what is barely sufficient to induce the people of those countries to save and accumulate. My meaning is, that it would require but a short time to reduce profits to the minimum, if capital continued to increase at its present rate, and no circumstances having a tendency to raise the rate of profit occurred in the meantime. The expansion of capital would soon reach its ultimate boundary, if the boundary itself did not continually open and leave more space.

IV.4.11

In England, the ordinary rate of interest on government securities, in which the risk is next to nothing, may be estimated [1848] at a little more than three per cent: in all other investments, therefore, the interest or profit calculated upon (exclusively of what is properly a remuneration for talent or exertion) must be as much more than this amount, as is equivalent to the degree of risk to which the capital is thought to be exposed. Let us suppose that in England even so small a net profit as one per cent, exclusive of insurance against risk, would constitute a sufficient inducement to save, but that less than this would not be a sufficient inducement. I now say, that the mere continuance of the present annual increase of capital, if no circumstance occurred to counteract its effect, would suffice in a small number of years to reduce the rate of net profit to one per cent.

IV.4.12

To fulfil the conditions of the hypothesis, we must suppose an entire cessation of the exportation of capital for foreign investment. No more capital sent abroad for railways or loans; no more emigrants taking capital with them, to the colonies, or to other countries; no fresh advances made, or credits given, by bankers or merchants to their foreign correspondents. We must also assume that there are no fresh loans for unproductive expenditure, by the government, or on mortgage, or otherwise; and none of the waste of capital which now takes place by the failure of undertakings which people are tempted to engage in by the hope of a better income than can be obtained in safe paths at the present habitually low rate of profit. We must suppose the entire savings of the community to be annually invested in really productive employment within the country itself; and no new channels opened by industrial inventions, or by a more extensive substitution of the best known processes for inferior ones.

IV.4.13

Few persons would hesitate to say, that there would be great difficulty in finding remunerative employment every year for so much new capital and most would conclude that there would be what used to be termed a general glut; that commodities would be produced, and remain unsold, or be sold only at a loss. But the full examination which we have already given to this question,*16 has shown that this is not the mode in which the inconvenience would be experienced. The difficulty would not consist in any want of a market. If the new capital were duly shared among many varieties of employment, it would raise up a demand for its own produce, and there would be no cause why any part of that produce should remain longer on hand than formerly. What would really be, not merely difficult, but impossible, would be to employ this capital without submitting to a rapid reduction of the rate of profit.

IV.4.14

As capital increased, population either would also increase, or it would not. If it did not, wages would rise, and a greater capital would be distributed in wages among the same number of labourers. There being no more labour than before, and no improvements to render the labour more efficient, there would not be any increase of the produce; and as the capital, however largely increased, would only obtain the same gross return, the whole savings of each year would be exactly so much subtracted from the profits of the next and of every following year. It is hardly necessary to say that in such circumstances profits would very soon fall to the point at which further increase of capital would cease. An augmentation of capital, much more rapid than that of population, must soon reach its extreme limit, unless accompanied by increased efficiency of labour (through inventions and discoveries, or improved mental and physical education), or unless some of the idle people, or of the unproductive labourers, became productive.

IV.4.15

If population did increase with the increase of capital, and in proportion to it, the fall of profits would still be inevitable. Increased population implies increased demand for agricultural produce. In the absence of industrial improvements, this demand can only be supplied at an increased cost of production, either by cultivating worse land, or by a more elaborate and costly cultivation of the land already under tillage. The cost of the labourer's subsistence is therefore increased; and unless the labourer submits to a deterioration of his condition, profits must fall. In an old country like England, if, in addition to supposing all improvement in domestic agriculture suspended, we suppose that there is no increased production in foreign countries for the English market, the fall of profits would be very rapid. If both these avenues to an increased supply of food were closed, and population continued to increase, as it is said to do, at the rate of a thousand a day, all waste land which admits of cultivation in the existing state of knowledge would soon be cultivated, and the cost of production and price of food would be so increased, that, if the labourers received the increased money wages necessary to compensate for their increased expenses, profits would very soon reach the minimum. The fall of profits would be retarded if money wages did not rise, or rose in a less degree; but the margin which can be gained by a deterioration of the labourers' condition is a very narrow one: in general they cannot bear much reduction; when they can, they have also a higher standard of necessary requirements, and will not. On the whole, therefore, we may assume that in such a country as England, if the present annual amount of savings were to continue, without any of the counteracting circumstances which now keep in check the natural influence of those savings in reducing profit, the rate of profit would speedily attain the minimum, and all further accumulation of capital would for the present cease.

IV.4.16

§5. What, then, are these counteracting circumstances, which, in the existing state of things, maintain a tolerably equal struggle against the downward tendency of profits, and prevent the great annual savings which take place in this country from depressing the rate of profit much nearer to that lowest point to which it is always tending, and which, left to itself, it would so promptly attain? The resisting agencies are of several kinds.

IV.4.17

First among them, we may notice one which is so simple and so conspicuous, that some political economists, especially M. de Sismondi and Dr. Chalmers, have attended to it almost to the exclusion of all others. This is, the waste of capital in periods of over-trading and rash speculation, and in the commercial revulsions by which such times are always followed. It is true that a great part of what is lost at such periods is not destroyed, but merely transferred, like a gambler's losses, to more successful speculators. But even of these mere transfers, a large portion is always to foreigners, by the hasty purchase of unusual quantities of foreign goods at advanced prices. And much also is absolutely wasted. Mines are opened, railways or bridges made, and many other works of uncertain profit commenced, and in these enterprises much capital is sunk which yields either no return, or none adequate to the outlay. Factories are built and machinery erected beyond what the market requires, or can keep in employment. Even if they are kept in employment, the capital is no less sunk; it has been converted from circulating into fixed capital, and has ceased to have any influence on wages or profits. Besides this, there is a great unproductive consumption of capital, during the stagnation which follows a period of general over-trading. Establishments are shut up, or kept working without any profit, hands are discharged, and numbers of persons in all ranks, being deprived of their income, and thrown for support on their savings, find themselves, after the crisis has passed away, in a condition of more or less impoverishment. Such are the effects of a commercial revulsion: and that such revulsions are almost periodical, is a consequence of the very tendency of profits which we are considering. By the time a few years have passed over without a crisis, so much additional capital has been accumulated, that it is no longer possible to invest it at the accustomed profit: all public securities rise to a high price, the rate of interest on the best mercantile security falls very low, and the complaint is general among persons in business that no money is to be made. Does not this demonstrate how speedily profit would be at the minimum, and the stationary condition of capital would be attained, if these accumulations went on without any counteracting principle? But the diminished scale of all safe gains inclines persons to give a ready ear to any projects which hold out, though at the risk of loss, the hope of a higher rate of profit; and speculations ensue, which, with the subsequent revulsions, destroy, or transfer to foreigners, a considerable amount of capital, produce a temporary rise of interest and profit, make room for fresh accumulations, and the same round is recommenced.

IV.4.18

This, doubtless, is one considerable cause which arrests profits in their descent to the minimum, by sweeping away from time to time a part of the accumulated mass by which they are forced down. But this is not, as might be inferred from the language of some writers, the principal cause. If it were, the capital of the country would not increase; but in England it does increase greatly and rapidly. This is shown by the increasing productiveness of almost all taxes, by the continual growth of all the signs of national wealth, and by the rapid increase of population, while the condition of the labourers is certainly not declining, but on the whole improving.*17 These things prove that each commercial revulsion, however disastrous, is very far from destroying all the capital which has been added to the accumulations of the country since the last revulsion preceding it, and that, invariably, room is either found or made for the profitable employment of a perpetually increasing capital, consistently with not forcing down profits to a lower rate.

IV.4.19

§6. This brings us to the second of the counter-agencies, namely, improvements in production. These evidently have the effect of extending what Mr. Wakefield terms the field of employment, that is, they enable a greater amount of capital to be accumulated and employed without depressing the rate of profit: provided always that they do not raise, to a proportional extent, the habits and requirements of the labourer. If the labouring class gain the full advantage of the increased cheapness, in other words, if money wages do not fall, profits are not raised, nor their fall retarded. But if the labourers people up to the improvement in their condition, and so relapse to their previous state, profits will rise. All inventions which cheapen any of the things consumed by the labourers, unless their requirements are raised in an equivalent degree, in time lower money wages: and by doing so, enable a greater capital to be accumulated and employed, before profits fall back to what they were previously.

IV.4.20

Improvements which only affect things consumed exclusively by the richer classes, do not operate precisely in the same manner. The cheapening of lace or velvet has no effect in diminishing the cost of labour; and no mode can be pointed out in which it can raise the rate of profit, so as to make room for a larger capital before the minimum is attained. It, however, produces an effect which is virtually equivalent; it lowers, or tends to lower, the minimum itself. In the first place, increased cheapness of articles of consumption promotes the inclination to save, by affording to all consumers a surplus which they may lay by, consistently with their accustomed manner of living; and unless they were previously suffering actual hardships, it will require little self-denial to save some part at least of this surplus. In the next place, whatever enables people to live equally well on a smaller income, inclines them to lay by capital for a lower rate of profit. If people can live on an independence of 500l. a year in the same manner as they formerly could on one of 1000l., some persons will be induced to save in hopes of the one, who would have been deterred by the more remote prospect of the other. All improvements, therefore, in the production of almost any commodity, tend in some degree to widen the interval which has to be passed before arriving at the stationary state: but this effect belongs in a much greater degree to the improvements which affect the articles consumed by the labourer, since these conduce to it in two ways; they induce people to accumulate for a lower profit, and they also raise the rate of profit itself.

IV.4.21

§7. Equivalent in effect to improvements in production, is the acquisition of any new power of obtaining cheap commodities from foreign countries. If necessaries are cheapened, whether they are so by improvements at home or importation from abroad, is exactly the same thing to wages and profits. Unless the labourer obtains, and by an improvement of his habitual standard, keeps, the whole benefit, the cost of labour is lowered, and the rate of profit raised. As long as food can continue to be imported for an increasing population without any diminution of cheapness, so long the declension of profits through the increase of population and capital is arrested, and accumulation may go on without making the rate of profit draw nearer to the minimum. And on this ground it is believed by some, that the repeal of the corn laws has opened to this country a long era of rapid increase of capital with an undiminished rate of profit.

IV.4.22

Before inquiring whether this expectation is reasonable, one remark must be made, which is much at variance with commonly received notions. Foreign trade does not necessarily increase the field of employment for capital. It is not the mere opening of a market for a country's productions, that tends to raise the rate of profits. If nothing were obtained in exchange for those productions but the luxuries of the rich, the expenses of no capitalist would be diminished; profits would not be at all raised, nor room made for the accumulation of more capital without submitting to a reduction of profits: and if the attainment of the stationary state were at all retarded, it would only be because the diminished cost at which a certain degree of luxury could be enjoyed, might induce people, in that prospect, to make fresh savings for a lower profit than they formerly were willing to do. When foreign trade makes room for more capital at the same profit, it is by enabling the necessaries of life, or the habitual articles of the labourer's consumption, to be obtained at smaller cost. It may do this in two ways; by the importation either of those commodities themselves, or of the means and appliances for producing them. Cheap iron has, in a certain measure, the same effect on profits and the cost of labour as cheap corn, because cheap iron makes cheap tools for agriculture and cheap machinery for clothing. But a foreign trade which neither directly, nor by any indirect consequence, increases the cheapness of anything consumed by the labourers, does not, any more than an invention or discovery in the like case, tend to raise profits or retard their fall; it merely substitutes the production of goods for foreign markets in the room of the home production of luxuries, leaving the employment for capital neither greater nor less than before. It is true, that there is scarcely any export trade which, in a country that already imports necessaries or materials, comes within these conditions: for every increase of exports enables the country to obtain all its imports on cheaper terms than before.

IV.4.23

A country which, as is now the case with England,*18 admits food of all kinds, and all necessaries and the materials of necessaries, to be freely imported from all parts of the world, no longer depends on the fertility of her own soil to keep up her rate of profits, but on the soil of the whole world. It remains to consider how far this resource can be counted upon, for making head during a very long period against the tendency of profits to decline as capital increases.

IV.4.24

It must, of course, be supposed that with the increase of capital, population also increases; for if it did not, the consequent rise of wages would bring down profits, in spite of any cheapness of food. Suppose then that the population of Great Britain goes on increasing at its present rate, and demands every year a supply of imported food considerably beyond that of the year preceding. This annual increase in the food demanded from the exporting countries can only be obtained either by great improvements in their agriculture, or by the application of a great additional capital to the growth of food. The former is likely to be a very slow process, from the rudeness and ignorance of the agricultural classes in the food-exporting countries of Europe, while the British colonies and the United States are already in possession of most of the improvements yet made, so far as suitable to their circumstances. There remains as a resource, the extension of cultivation. And on this it is to be remarked, that the capital by which any such extension can take place, is mostly still to be created. In Poland, Russia, Hungary, Spain, the increase of capital is extremely slow. In America it is rapid, but not more rapid than the population. The principal fund at present available for supplying this country with a yearly increasing importation of food, is that portion of the annual savings of America which has heretofore been applied to increasing the manufacturing establishments of the United States, and which free trade in corn may possibly divert from that purpose to growing food for our market. This limited source of supply, unless great improvements take place in agriculture, cannot be expected to keep pace with the growing demand of so rapidly increasing a population as that of Great Britain; and if our population and capital continue to increase with their present rapidity, the only mode in which food can continue to be supplied cheaply to the one, is by sending the other abroad to produce it.*19

IV.4.25

§8. This brings us to the last of the counter-forces which check the downward tendency of profits, in a country whose capital increases faster than that of its neighbours, and whose profits are therefore nearer to the minimum. This is, the perpetual overflow of capital into colonies or foreign countries, to seek higher profits than can be obtained at home. I believe this to have been for many years one of the principal causes by which the decline of profits in England has been arrested. It has a twofold operation. In the first place, it does what a fire, or an inundation, or a commercial crisis would have done: it carries off a part of the increase of capital from which the reduction of profits proceeds. Secondly, the capital so carried off is not lost, but is chiefly employed either in founding colonies, which become large exporters of cheap agricultural produce, or in extending and perhaps improving the agriculture of older communities. It is to the emigration of English capital, that we have chiefly to look for keeping up a supply of cheap food and cheap materials of clothing, proportional to the increase of our population; thus enabling an increasing capital to find employment in the country, without reduction of profit, in producing manufactured articles with which to pay for this supply of raw produce. Thus, the exportation of capital is an agent of great efficacy in extending the field of employment for that which remains: and it may be said truly that, up to a certain point, the more capital we send away, the more we shall possess and be able to retain at home.

IV.4.26

In countries which are further advanced in industry and population, and have therefore a lower rate of profit, than others, there is always, long before the actual minimum is reached, a practical minimum, viz., when profits have fallen so much below what they are elsewhere, that, were they to fall lower, all further accumulations would go abroad. In the present state of the industry of the world, when there is occasion, in any rich and improving country, to take the minimum of profits at all into consideration for practical purposes, it is only this practical minimum that needs be considered. As long as there are old countries where capital increases very rapidly, and new countries where profit is still high, profits in the old countries will not sink to the rate which would put a stop to accumulation; the fall is stopped at the point which sends capital abroad. It is only, however, by improvements in production, and even in the production of things consumed by labourers, that the capital of a country like England is prevented from speedily reaching that degree of lowness of profit, which would cause all further savings to be sent to find employment in the colonies, or in foreign countries.*20
